What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Background: Resistance to cisplatin (DDP) in patients with ovarian cancer (OC) poses a great challenge to improving the quality of life of patients. Past reports have revealed that naringin can induce apoptosis of OC cells and delay the occurrence of drug resistance in OC cells. However, the molecular role by which naringin inhibits DDP resistance in OC has not been definitively proven by researchers. The objective of this study is to investigate the effect of naringin on DDP resistance in OC cells and the specific mechanism of naringin mediating autophagy. Methods: 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assay and flow cytometry were selected to evaluate the role of naringin or DDP on the proliferation and apoptosis of human OC cells (SKOV3/A2780). The protein levels of Sequestosome 1 (SQSTM1/p62, hereinafter referred to as p62), microtubule-associated protein 1 light chain 3 (LC3), transforming growth factor-β2 (TGF-β2) and SMAD family member 2 (smad2) were detected with Western blotting assay. Immunofluorescence assay was also used to evaluate the level of LC3 in different groups of cells. Besides, functional analyses were performed in vivo. Results: Naringin was shown to promote DDP sensitivity and apoptosis of human OC DDP-resistant cell line (SKOV3/A2780-DDP cells). Significantly increased p62 expression and reduced LC3 expression were found in naringin-treated cells. The autophagy agonist, rapamycin, reversed the effect of naringin on the resistance of SKOV3-DDP cells to DDP. Naringin inhibited levels of TGF-β2/smad2 pathway-related proteins, and regulated autophagy in SKOV3-DDP cells. Conclusions: In summary, naringin inhibits DDP resistance in OC cells by inhibiting autophagy mediated by the TGF-β2/smad2 pathway.
